Calibration method for image processing device, calibration device, image processing device, and display module

摘要

A method for calibrating an image processing device performs first processing to first image data, using a three-dimensional lookup table, and performing second processing to image data that has been processed by the first processing, using a one-dimensional lookup table on the output side of the three-dimensional lookup table. The method includes first setting step for setting first calibration information for each color component to have a target color temperature at the one-dimensional lookup table, second setting step for setting second calibration information for mapping the first image data to a target color space at the three-dimensional lookup table, and correction step for correcting the first calibration information based on an error from a target characteristic using image data that has been processed by the second processing.

1. A method for calibrating an image processing device including a three-dimensional lookup table and a one-dimensional lookup table provided on an output side of the three-dimensional lookup table, the method including performing first processing to first image data, using the three-dimensional lookup table, and performing second processing to image data that has been processed by the first processing, using the one-dimensional lookup table, the method comprising:
first setting step for setting first calibration information for each color component to have a target color temperature at the one-dimensional lookup table; second setting step for setting second calibration information for mapping the first image data to a target color space at the three-dimensional lookup table; and correction step for correcting the first calibration information based on an error from a target characteristic, using image data that has been processed by the second processing.
